The noun vet is short for either veteran (of the Armed Forces) or veterinarian (animal doctor).

Although "vet" is commonly used as an abbreviation in all English-speaking countries, the occupation is formally referred to as a veterinary surgeon in the United Kingdom and Ireland and now as a veterinarian in most of the rest of the English-speaking world.
